Would like to reuse a piston that appears to have no major signs of damage or wear. There is a bit of carbon built up on the top though.
What is a safe way to clean the it?

I've always used a scotchbrite pad and PB Blaster (or similar).

Yes, light scrubbing and some light lube will take it off.

I cheat and use the wire wheel on my bench grinder...it's a "soft" one and I'm VERY careful!

Looking good there my friend. Don't forget the ring lands as the build-up looked fairly heavy. |

I just popped the rings off to look and there is a bit of gunk and junk in there. More elbow grease! No cheats!

The recessed areas were the rings sit. 😁

I found it easiest to just use a little bit of SeaFoam, it is good at dissolving and lifting carbon deposits easily

I typically do it 2 ways. 1, if i'm doing a complete restoration i'll let the piston and crank case soak for 24 hours (depending on how much carbon build up there is). or 2, like i did for my Stihl MS460 and Husqvarna 137, I simply run it through the engine adding a small amount and letting it burn off before adding more. I typically add enough so the engine bogs down, but doesn't die. I will do this process until i have gone through 1/3 - 1/2 the can. |

Guess I'm mean.....I used a wire wheel very gently.

Awesome! Three methods that work good. That’s what I really like about this site. There always a different and possibly better way to do something. You just have to ask!
